This invention relates to arail formed in two longitudinal sections, the base portion forming one section and the tread portion .i'orining the other section.

The invention also relates to the particular construction of these sections by which they are interlocked.

The object of the invention is a rail strong and durable easily and quickly placed in position, readily repaired by the replacing of a new section when any section alreadyin' place becomes worn; and a further object of the invention is to reduce the cost of railroad construction by avoiding the use of fishplates, anglebars, tie plates, outside braces on curves, and the long bolts employed in. connection with fish-plates and other railroad joints.

The invention consists in the novel features of construction and combination of parts hereinafter described particularly pointed out in the claim, and. shown in the accompanying drai'vings, in which Figure 1 is a complete rail shown in per s ective, the Fig. 2 is a perspective view of t e base section, the upper or tread section being removed. Fig. 3 is a vertical section through the rail, the two sections being in position. Fi i is a plan view oi a portion of one of the base sections. 7

ln constructing my rail. 1 manufacture the same in two longitudinal sections, thereby providing a bed, base or lower section A, and an upper, tread section A. As these two sections are readily detachable they will be described so arately. The lower section A consists of a ase ortion proper as shown at B. This portion3 has a broad, liat under face and is adapted'to rest upon and be spiked to the cross ties in the usual manner.

Between its side edges it is thickened by the formation of a longitudinal ridge B the longitudinal center f the ridge being on the outer side of the longitudinal center of the base portion B. Adjacent its inner side this ridge B is longitudinally grooved as shown at C and the outer wall of the groove is extended upwardly to form the inner face of a Web i is radually reduced in thickness ti.

web D carried 1) the ridge B and extending longitudinally a ong the ridge parallel to and adjacent the groove C. .lt will understood that the ridge, groove and web above mentioned extend the entire length of the lower, base section B of the rail. The web D has an outer perpendicular face but the inner face commencing from the bottom ot'th groove C and extending to the upper edge of the web D is outwardly inclined, the web I) being approximately two-eighths of aninch thicker at its base than at its top. The up or edges of the web D are not sharp corners ut are slightly rounded as at D, the object of which will be stated hereafter. "The inner wall of the groove G is also upwardly angled having the same degree of inclination that is given to the opposite, outer wall of the groove, but of course in the opposite direction. The groove C is therelore wedgeshape in crossv section.

The tread portion or upper section A co:-- sists of the tread proper E which carries a depending web F, the upper section. A being T-shaped in cross-section. The depending ward its lower edge, being Wedge-shaped in cross section, and rests in the groove C the underside of the tread portion on each side of the web F being grooved as shown at G, and

.the upper ed e portion of the web i rests in one of these grooves. it w'll be obvious that by this construction the upper section A is reversible, and that either face of the web F is adapted to bear on the inner, inclined face of the Web D, and either groove G is adapted to receive the upper portion of the Web D. The grooves G have their bottoms slightly rounded adjacent the sides oi the grooves to fit the rounded edges of the Web 3 as shown at D, the object of this being to save the expense of milling the edges to form a sharp corner, and to prevent anyrattling or bettering down of the rail.

The Web D is formed with a plurality of elongated bolt openings shown at D while the web F has formed in it the usual circular bolt holes, and the two sections A-and A are secured together by suitable bolts and nuts. Owing to the absence of fish plates, angles bars and braces, the bolts are of much less Weight than the ordinary rail road bolt, being inuchshorter, and a considerable saving is thus effected.

in operation the upper sections A are arvi'ill give a rigid construction independent of ranged so thetthe said upper sections will overlap the meeting ends of the lower scctions ii and in this manner 2. continuous rail is practically formed. The meeting ends of both the upper and lower sections, or of either section, may be squared or beveled or angled in any desired manner as may be found most desirable.

By employing s rail as herein described. the Work of construction is greatly facilitated as the base sections may be laid in place by one gang of men followed by a second gang engaged in fitting the upper sections in position, these sections being lighter and more easily handled than the usual solid, one piece rail. By having the bolt opening of the base section elongated allowance is made for proper adjustment of the upper section, and lor expansion and contraction.

Repair work is readily accomplished as any of the sections A forming the track can. be readily detached from their base sections and lifted out of piece, and a new section put in position, Without the necessity of extracting the spikes from the ties and rernoving'iish plates and taking up the entire rail, as with rails now in ordinary use. it will be obvious that the Wedging of the two sections together the bolts, and furthermore that e greet edvantage is gained by so constructing the upper section A that it is reversible as it is ssaeee therefore adapted for use upon either the right or left hand side of the track, and when a. tread section is to be placed in position it is z not necessary to consider the side of the track upon which it is to be placed, and pick out some special section, as would be the case if the upper sections Were not reversible.

Having thus fully described my invention What I claim as new and desire to secure by Letters Patent is:

A rail having a base provided with an up Wardly extending web having curved upper edge to one side of the longitudinal center and a longitudinal groove parallel to said Web having inclined side Walls and a square bottom, the outer face of the groove being continuous with the inner face of the web, the said face. being outwardly and upwardly in ned Q the 'mesngle asthe-inner side Wall o'l vided with a central longitudinal Web having downwardly converging feces and a square end adapted to fit in the groove of the base and the seidraii having longitudinal grooves formed iiiits under face on'esch side of the web having conca'ved tops in which the rounded end of the Web carried by the base is adapted to fit.
